Abstract
Un système laser comprend une diode laser qui, lors de son activation, produit sélectivement une onde continue de lumière laser ou des impulsions intermittentes espacées uniformément de lumière laser. Le système comprend en outre un dispositif de focalisation laser doté d'une pluralité de lentilles qui focalisent la lumière laser produite par la diode laser et dirigent la lumière laser vers un résonateur optique. Le résonateur optique comprend un milieu laser qui, lorsqu'il est coupé par la lumière laser provenant de la diode laser, produit un faisceau de lumière laser ayant une longueur d'onde qui peut être utilisée pour un traitement thérapeutique. Le système peut fonctionner pour produire la lumière laser thérapeutique lorsque la diode laser fonctionne soit en mode d'onde continue, soit en mode pulsé, sans déplacer les composants du système l'un par rapport à l'autre.
